DHS Office of the Chief Security Officer

The DHS Office of the Chief Security Officer, operating under the Contract Administration Services Division (70RCAS), plays a pivotal role in advancing the Department of Homeland Security’s mission by overseeing the acquisition of critical professional, scientific, and technical support services. This office ensures the integrity and operational readiness of DHS systems through the strategic procurement of contract services that reinforce cybersecurity, physical security infrastructure, and engineering systems. Their portfolio primarily consists of non-personal services requiring specialized expertise in systems integration, risk assessment, and mission-critical support, often involving complex performance-based requirements aligned with national security standards. Contractor relationships are broad and diverse, encompassing firms with deep domain expertise in security operations, systems engineering, and technical advisory services. While no single contractor dominates the award landscape, the office maintains a consistent pattern of engaging qualified vendors capable of delivering high-assurance, scalable support across federal facilities and cyber-physical environments. Relationships are typically performance-driven, emphasizing compliance with federal acquisition regulations, rigorous quality assurance protocols, and continuous service delivery metrics. The office maintains a strong preference for full and open competition, with 100% of its acquisitions designated as “No Set-Aside,” reflecting a focus on technical capability and mission alignment over socioeconomic classifications. This approach prioritizes selecting the most qualified provider based on merit, performance history, and compliance with stringent security clearance and operational requirements. The primary NAICS code focus—561990 (All Other Support Services)—indicates a specialization in niche, non-standardized support functions essential to DHS operations. These include security consulting, technical analysis, facility protection services, and integrated systems support. The office’s procurement strategy centers on acquiring specialized expertise that complements DHS’s core missions in threat mitigation, infrastructure resilience, and operational continuity, often requiring contractors with cleared personnel and proven experience in federal security environments.
